While the tain novel features of construction, combination, mold is in its upper position, the slug and type .55. and arrangement of parts and portions as wi1l are cast, while the mold is in its lower position, the newly formed slug and type are removed.

It will be noted that the table T is of the conventional hinged type.

The slug length control bar 2 is slidably mounted adjacent the under side of t .e table top T and extends forwardly from the opening Tl therein. The portion of the control bar adjacent its extremity is increased in height, as in dicated by 2a, so as to project into the opening T1 and terminate flush with the upper face of the mold, shown in Fig. 6. When the control bar is in its forward position, the upwardly projecting portion 2a is adjacent the forward margin of the opening T1. The lower surface of the control bar 2 is smooth, and is adapted to close the outlet holes of a casting mouthpiece P1 of a type metal casting pot P, which would otherwise cast the excess length of slug. Forwardly the projection 2a, the bar clears the under side of the table T.

At its forward lower portion the bar 2 is provided with a laterally extending web 22). The web 2b is connected preferably integrally with a guide member 3 which extends in parallel disposed relation with the slug length control bar 2 and in offset relation to the slot T1 of the table top.

The guide member 3 is substantially rectangular in cross section, and is provided with "idges 3:; along its side margin. These ridges 3a are adapted to be slidably mounted in channels 4a of guide keeper members i. The guide keeper members 4 are secured to the under side of the table top, as shown best in Figs. 1, 2, 3, and 4.

One of the guide keeper members, preferably the one remote from the control bar 2, in addition to functioning as a guide keeper member, forms a base for a shaft mechanism. This base portion, designated 4b, is arranged toward the forward portion of the keeper member along the side thereof. Formed in the base portion 4b is a slot ic arranged in parallel disposed relation with the line of travel of the control bar. Bordering the slot 4c along the under face of the base ib, there is formed a rack 4d.

The slot 40 is adapted to receive a shank 5, to the lower end of which is attached a stop member 6. The upper face of the stop member 6 is provided with teeth 6a which are adapted to fit in the teeth of a section of the rack 401, as shown in Figs. 3 and 4.

The upper end of the shank 5 is provided with a fixed grip 5a having a pointer 5b extending laterally therefrom adjacent the top of the table. The pointer 5b is adapted to register with a scale plate '7, which is affixed to the top of the table T, as shown best in Figs. 1, 2, and 3.

Supported at the upper end of the shank 5 is a movable grip 8, which is in the form of a cam lever with an arm portion 8a arranged opposite the fixed grip 5a. Between the two grips there is provided a spring Sb, which tends to force the grips apart, and by so doing holds the teeth of the stop 6 in engagement with the rack. Shifting of the movable grip 8 towards the fixed grip 5a, permits sli ht downward shifting of the shank 5 and disengagement of the teeth 6a with the rack so that the stop may be shifted therealong to the desired position. The markings of the scale correspond to the teeth of the rack so that the stop may be positioned accurately.

Arranged on the under side of the guide memher 3, adjacent its forward end, is a depending lug 9, which is adapted to be engaged by the forked extended end 10a of a lever member 10. The lever 10 is supported by the table top T and extends sidewise adjacent the under side thereof and within the frame, designated F, which supports the table top. The lever 10 is rotatably mounted upon a stub shaft 11a which depends from a supporting plate 11 secured to the under side of the table top near the side margin of the frame F, as shown in Figs. 1 and 5. Also depending from the support 11 is a stub shaft 1122 upon which is rotatably mounted a segmental gear 12. The teeth of the segmental gear 12 are adapted to engage a segmental gear portion, designated 10b, arranged at the opposite extremity of the lever 10 from the forked end 10a thereof. The lower surface of the segmental gear 12 is provided with an annular cam portion 12a, which is adapted to fit in a complementary cam portion 130. of a sleeve member 13. One cam portion is provided with a projection, while the other portion is provided with a corresponding depression, as shown in Fig. 5, and in the diagrammatical view, Fig. 7. Thus, the two cam portions are normally interlocked. However, the table top is free to be lifted from the frame F.

The sleeve member 13 is supported in a vertical position by a suitable bearing l i attached to the frame in any suitable manner.

The sleeve 13 is slidably mounted upon a shaft 15, but is keyed against rotationrelative thereto. The shaft 15 is journalled at its lower end portion in a bearing 16. Between the bearings 14 and 16, there is mounted a tension spring 17. This is supported at its end portion in spring retaining washers 17a. The lower end of the sleeve member 13 is flush with the lower end of the bearing 14 and engages the uppermost washer 17a, so that downward movem nt of the sleeve member past the lower end of the bearing 14, compresses the spring 17, as shown in Fig. 5.

Attached to the lower end of the shaft 15, is a lever 13, which extends rearwardly within the frame F to a point opposite a cam shoe mechanism M, which supports the type metal containing pot and shifts it in the desired manner. At this end, the lever 17 is connected by a link 18 to a bracket 19, which is fixed to the cam shoe mechanism M. This connection between the lever 18 and bracket 20 is such as to allow vertical movement of the mechanism M without causing an appreciable rotation of the shaft 15. However, lateral movement of the cam shoe mechanism M on its cam C produces an arcuate movement of the shaft 15, which is more than sufiicient for the extreme movement of the slug length control bar 2.

Operation of our line casting slug length control is as follows:

The stop member 6 is set so that when it is engaged by the lever member 10, the length of the slot between the extremity of the bar 2 and the fixed end of the slot 1a, is of the desired amount. When the type metal containing pot P is being shifted to the position for casting, the various levers and shafts connected with the slug length control bar 2 shift the control bar inwardly until the stop 6 is engaged by the lever member 10. Further movement causes the sleeve 13 and cam portion 13a to shift relative to the cam portion 12a, compressing the spring 1'7. The force of the spring transmitted through the cams and lever 10 is more than sufiicient to hold the slug length control bar firmly in place during the casting operation.

The upward movement of the slug casting mold I is in advance to. the shifting of the type metal containing pot so that the mold is in its upper position against the matrix M before the slug length control bar begins to enter therein. Thus, the control bar 2 is moved. endwise with respect to the slot 1a and in no wise strikes the corners. between the slot 101, and the upper face of the casting mold.

It: will be noted that the movement of the control bar 2'. is so turned as to both enter and withdraw from the mold, while the mold remains in its. upper position,

It is preferred to have the extreme outer position of the control bar 2 as close to the end of the slot. id as possible so that even though there should be no movement of the control bar due to an obstruction, there would be but a very small space between the control bar and the mold through which the molten type metal might squirt, thus eliminating any danger of an accident. A further arrangement is accomplished by limiting the outward position of the stop member 6, sov that even though it is not set, the length control bar will move in far enough to cast the maximum length of slug which the machine is adapted to produce.

This. arrangement has the further advantage that the setting of the machine for full size slugs, which are most often wanted, may be made merelyby shifting the stop to. its extreme position.
